The QH Timber was designed to be a deep, nasally, wet blowing, soft, ultra realistic call that is easy for average caller to replicate the pure sounds of an ol'sassy mallard hen. The advantage of the Timber call is its ability to produce softer nasally quacks and pure duck sounds with less effort due to its built-in back pressure and unique tone board design. This is the perfect call for situations when realistic, nasty calling is a must. Single Reed. Bocote wood/Polycarbonate.
